MEANS'RELATING TO THE MANUFACTURE or unseen warns. secretes.

Original application filed March 21, 1927, Serial 150. 177,010. Divided and this application filed August 253,

1927. Serial No. 214,876.

My present invention relates to an apparatus for securing hardv rubber ferrules in the necks of water bottles, made of soft or flexible rubber, the ferrules being adapted to receive the screw closure plugs.

The invention aims to provide an improved means by which such bags may have the ferrules expeditiously and firmly secured therein without damage to the neck of the bag through application of too much heat thereto, and the invention comprises the novel means hereinafter described and defined by the appended claim.

In order that the invention may be better understood reference is made to the accompanying drawing in which Fig. 1 is a sectional view through the neck of a bottle with the ferrule in place therein.

Fig. 2 is a sectional view of the heat transmitting element and a portion of a soldering iron engaged therewith.

Referring by reference characters to this drawing, the numeral. 1 designates the neck of a water bottle of the usual type and 2 the hard rubber ferrule adapted to fit within t e neclt and having a threaded bore 2 to receive the usual closure plug or stopper (not shown). Before the ferrule is inserted in the neck, either the internal surface of the neck or the corresponding exterior surface of the ferrule,

is provided with a coating of vulcanizable rubber cement of known character, where after the ferrule is inserted in the neck into the position shown in Fig. 1.

To effect the vulcanization of the cement, I provide an element 3 having a reduced portion provided with schew threads 3 adapted to screw into the threaded bore of the hard rubber ferrule and having'in its larger end an internally screw threaded axialrecess. The

, electric soldering irons in common use are provided with threaded ends upon which are screwed removable soldering tips as is well known. I

The forward end of such soldering iron is replace the usual soldering tip, its bore orly threaded portion adapted to screw into shown conventionally t in Fig. 2. To enable such a soldering iron to be used to carry out my process the element 3 is adapted to 3? being adapted to screw onto the threaded end 4* of the iron l after the tip has been removed.

The element 3 is made o'tg'ood heat conducting material-such as'brass or bronze for example and, having been applied to the soldering iron and screwed into the hard rubber ferrule with the latter in place in the bottle neck, the el stric current is turned on regulated to produce the proper degree of heat), which heat is transmitted. to and through the hard rubber ferrule until the cement is completely cured. /Vhile this istaking place the neck of the bottle has its exterior exposed to the air which constitutes a cooling fluid.

1 have found that by this method an d. means the necessary heat may be applied without detriinentally affecting the hard rubber. ferrule and without danger of damag' the soft rubber neck, towards which the air-exposure contributes. V

Obviously the ferrule may be applied to the element 3 while the latter is in place on the soldering iron tip (before .theheating current is turned on) andthe soldering iron used a convenient handle for inserting the ferrule in the neck. V

This application is adi-vision of my copending application #177,010 Mar. 21, 1927 now Patentlfii lfil?) Oct. 11, 1927.

What I claim is:

. Means for ef ecting the vulcanization of the cementbetween the necks of water bottles and the hard rubber ferrules therein, having}: threaded bores, comprising a tip ineinberof heat conducting" material having an exterian the ferrule and having an interiorly threaded portion adapted'to screw onto the end of the ordinary electric soldering iron.

In testimony whereof, I aflix my signature.
